<span> 2018 has four positive factors, i.e., 1, 2, 1009 and 2018.</span>
Answer: first blank is 4/25.
second blank on the top row is 16:100=4:25.
First blank on the second row is 13/50.
The second blank on the second row is 26:100=13:50.
The first blank on the third row is 33:50.
The first blank on the fourth row is 4/7.
The second blank on the fourth row is 57%.
The third blank is 0.57.
Step-by-step explanation:
16/100 simplified is 4/25. 16÷4=4 100÷4=25
ratios are also fractions.
26/100 simplified is 13/50. 26÷2=13 100÷2=50
66/100 simplfied is 33/50. 66÷2=33 100÷2=50
4÷7(rounded down)=0.57
I had this question before. The answer is 128 :)
Answer:
B. 9 yards
Step-by-step explanation:
you just have to add the oak to pine and pine to end then you subtract the total of maple to end.
Answer:
D is the similar triangle
Step-by-step explanation:
A quick solution to this problem is using the hypotenuse.
You know that sin(A) is 1/4 and sin is opposite / hypotenuse, so the hypotenuse should be a multiple of 4 in order for the fraction to reduce to 1/4. (it might not be, but I usually do this to see if there's a quick solution)
Using this trick, you find that the only triangle with a hypotenuse that is a multiple of 4 is the last triangle. Now simply double check the other trig. functions to check whether it truly is the same.
To check each trig function, you must first determine the corresponding angle to angle A. Again, for simplicities sake, let's use 1/4 as a determiner for the angle. The only combination of sides divided by hypotenuse that simplifies to 1/4 is 6/24. Therefore 6 must be opposite to the angle, since it's sin(a) = 1/4 and sin is opposite / hypotenuse. So the angle is X.
Now check for both cos and tan
Cos(x) = 6(15)^0.5 / 24 = (15)^0.5 / 4 CHECKS OUT
Tan(x) = 6 / 6(15)^0.5 = 1 / (15)^0.5 CHECKS OUT
Since everything checks out, then answer D is truly correct.
